That just goes to class set 2 then backDid you get a recovery done? Did you get an unlock all done with that recovery? I'm going to assume your on Xbox 360!
If you did get an unlock all and recovery then try going to the custom game menu and open up your custom classes are the class names random symbols? If they are then press RB then LB and the class names should go back to normal then hopefully it should work.
If it does not work or you have any other questions feel free to PM me and I will try to help you out!
